Yes Bings. I'm pretty handy. I have the Bings one turn out on the idle air screw and it starts easy but it's very lumpy at idle hot or cold. While I'm riding it runs well and pulls hard from all gears. Between 4000 and 6000 rpms it's smooth as glass.

Do all the tuning things as recommended by these fabulous inmates. Old gas, water, and corrosion can easily mess up the idle circuit. I would take the Bings off, disassemble and thoroughly clean 'em. After installing and adjusting, check for vacuum leaks - that will affect idle. Points work fine; they are simple. I have the Boyer system and it has been reliable for many years.
